Efficient separation of photogenerated charges at the surface of photocatalysts is vital for achieving high photocatalytic activity. Here, a Bi/BiNbOCl heterostructure piezo-photocatalyst with an amorphous/crystalline interface (acBi/BNC) is prepared by in situ reduction using BiNbOCl as a self-sacrificial template. This ingenious design synergistically utilizes the advantages of the amorphous/crystalline interface structure, localized surface plasmon resonance effect, and piezoelectric field.

Introduction: China implemented a dynamic zero-COVID strategy to curb viral transmission in response to the coronavirus disease 2019 (COVID-19) pandemic. This strategy was designed to inhibit mutation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for COVID-19. This study explores the dynamics of viral evolution under stringent non-pharmaceutical interventions (NPIs) through real-world observations.

Article Synopsis
  • C-reactive protein (CRP) is an important inflammation biomarker linked to various diseases, making its accurate detection critical for diagnosis and treatment.
  • A new label-free near-infrared (NIR) fluorescence aptasensor using an anthracene derivative and a molybdenum disulfide platform was developed to detect CRP with high sensitivity and specificity.
  • This aptasensor can directly measure CRP in human serum samples, surpassing previous methods that only worked with artificially spiked samples.

Intense anthropogenic activities in a karst area will inevitably change the regional groundwater environment and affect the characteristics of the karst groundwater, such as the hydrochemistry and water quality. It is of great importance to study the evolution characteristics of the hydrochemistry and water quality of karst groundwater under intense anthropogenic activities to ensure the stability and sustainable development of karst ecosystems. In this study, a representative synclinal basin-type karst groundwater system in northern China was used as the study object, and the effects of intense anthropogenic activities on the evolution of the hydrochemistry and water quality of the karst groundwater were analyzed using a comprehensive application of a groundwater quality assessment, a multivariate statistical analysis, a hydrogeochemical analysis, and multi-factor regime monitoring of the karst groundwater quality.

Fluorination has emerged as a promising strategy in medicinal chemistry to improve the pharmacological profiles of drug candidates. Similarly, incorporating fluorinated non-canonical amino acids into macrocyclic peptides expands chemical diversity and enhances their pharmacological properties, from improved metabolic stability to enhanced cell permeability and target interactions. However, only a limited number of fluorinated non-canonical amino acids, which are canonical amino acid analogs, have been incorporated into macrocyclic peptides by ribosomes for construction and target-based screening of fluorinated macrocyclic peptides.

The performance of next-generation particle accelerators has been adversely affected by the occurrence of electron multipacting and vacuum instabilities. Particularly, minimization of secondary electron emission (SEE) and reduction of surface resistance are two critical issues to prevent some of the phenomena such as beam instability, reduction of beam lifetime, and residual gas ionization, all of which occur as a result of these adverse effects in next-generation particle accelerators. For the first time, novel quinary alloy Ti-Zr-V-Hf-Cu non-evaporable getter (NEG) films were prepared on stainless steel substrates by using the direct current magnetron sputtering technique to reduce surface resistance and SEE yield with an efficient pumping performance.
